Fig. VI-8. Generalized isopach of Desert Creek cycle of the Upper Hermosa Formation.
From Peterson and Ohlen (1963, Fig. 12) after Peterson (1959). Interval isopached (25 foot
contours) is the carbonate-evaporite sequence between black shales. The map outlines the
carbonate buildup forming the Aneth field. The trend is irregular but crudely aligned north-
west-southeast parallel to the strike of facies around the Paradox basin. Illustration courtesy
